Hollywood starlet Lindsay Lohan collapsed on Wednesday afternoon after suffering from heat exhaustion. The 20-year-old was rushed to an emergency room in LA from the set of her new movie, `Georgia Rule’. “She was overheated and dehydrated after filming in 105-degree weather for 12 hours,” Lindsay’s rep reports, adding that she spent a couple of hours in the hospital after being given a Vitamin B shot. Lindsay is expected to return to the set tomorrow, where she plays a rebellious teenager who’s dysfunctional mother (Felicity Huffman) sends her to spend the summer with her grandmother (Jane Fonda).
